TWINE-CAN FOR GRAlN-BlNDERS.

SPECIFICATION forming part of Letters Patent No. 745,835, dated December 1, 1 903.

Application filed July 6, 1903.

T0 aZZ whom, it may concern.-

Beit known that I, PAUL HANSON, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Twine-Can for Grain-Binders, of which the following is a specification.

This invention relates to twine-cans for grain-binders, and is designed as an improvement upon the invention set forth, described, and claimed in my pending application, Serial No. 124,487, filed September 22, 1902.

The object of the invention is to simplify and improve the construction of devices of this nature and to render the same more effective in operation.

A further object of the invention is to provide means for preventing the twine from unraveling or unwinding at the end of the cop or ball of twine and becoming wedged around the pintle or gudgeon upon which the center pin which holds the cop or ball of twine is mounted.

A further object of the invention is to provide means whereby the can is adapted for use for grass binder-twine as well as for ordinary Manila binder-twine.

A further object of the invention is to provide a tension device for the twine.

A further object of the invention is to provide means for efficiently supporting the twine-can.

Other objects of the invention will appear more fully hereinafter.

The invention consists, substantially, in the construction, combination, location, and

- arrangement of parts, all as willbe more fully Fig. 1, showing the construction and arrangement when the can is employed for ordinary Serial No. 164,448. (No model.)

binder-twine. Fig. 4 is a top plan view of the construction shown in Fig. 3. Fig. 5 is a detached detail view inperspective of the sleeve employed 1' or preventing the unraveling or unwinding of the cop of twine at the end thereof. Fig. 6 is a View in horizontal section on the line 6 6, Fig. 1, looking in the direction of the arrows.

The same part is designated by the same reference-sign wherever it occurs throughout the several views.

In the drawings reference-sign A designates the can or casing proper, provided with a top B.

G designates a central pin adapted to reoeive the cop or ball of twine when grass binder-twine is employed, the cop or ball being slipped or sleeved upon the supportingpin 0.

D designates the tension-arm, through the outer or free end of which the twineis reeled; E, the spring through which tension is applied to said arm in a direction to normally press the free end thereof toward the side of the can; F, the bottom plate secured to the lower end of pin C; G, the cam actuated by the swinging movement of arm D to engage or release or to form a brake for the end plate F, and H the end plate arranged at the upperend of the supporting-pin C and pressed toward the same by means of spring J.

The parts so far described may be of the same construction and relative arrangement, except in the particulars hereinafter to be noted, as set forth in my prior application,

above referred to, and in the specific details of construction thereof form no part of my present invention.

In the operation of a twine-can embodying the principles above set forth it has been found that the danger is incurred of the twine unreeling from the cop or ball and wedging in between the upper end of the cop or ball and the under surface of the end plate H and thence winding around the pintle or stud forming the journal upon which the center pi'n O revolves, thereby requiring an undue strain upon the twine in order to unwind the same or to revolve the cop or ball, and hence frequently resulting in a breakage of the twine.

It is among the special purposes of my present improvement to avoid the objection noted, and I will-now describe the means for accomplishing this result.

K and L designate gudgeons or dowel-pins fixed in the respective ends of the center pin 0 and in axial alinement with each other and forming the pivots for the center pin 0. The gudgeon K when the can is used for grass binder-twine passes through an opening in the bottom M of the can or casing and is journaled in a bearing N, formed in a supportingbracket 0. The gudgeon or pin L, fixed in the upper end of the center pin 0, passes through a bearing or opening serving as a bearing formed in a casting or plate P, mounted upon the top orcap B. The spring J, which presses the upper end plate H upon the end of the cop or ball of twine when placed in position upon the center pin, is mounted upon this gudgeon L.

Q designates a contractible sleeve having lugs R at the upper end thereof arranged to pass through slots or openings formed in the end plate H and to be bent laterally, so as to form a support for the sleeve Q, as clearly shown in Fig. 1. This sleeve is split, so that the internal diameter thereof can be contracted or expanded, as may be desired, and tits over the upper end of pin 0 and projects into the central opening of the cop or ball of twine when placed in position. The respective edges of the split sleeve Q are provided with bent lugs S, the bent lug S on each edge forming a guide for the other and cooperating edge -to guide said edges in the contracting or expanding movements of the sleeve. This sleeve is made exteriorly tapering or conical, the upper end having the largest diameter and fitting or projecting down into the central opening of the cop or ball of twine forms a bearing for the twine and being contractible in internal diameter is adapted for cops or balls having varying diameters of the internal bore thereof. The provision of this sleeve prevents the twine from becoming unraveled or unwound from the upper end of the cop or ball of twine and wedging in between the upper end of the pin 0 and around the gudgeon L, thereby relieving the twine of the strain or pull exerted thereon, which is necessary to rotate or unwind the twine, such as would result if the twine should become wrapped around the pintle orgudgeon L.

In adapting the can to the double purpose of ordinary Manila binder-twine and grass bindertwine, which on account of its increased size or diameter is usually produced in cops or balls of greater size than that of cops or balls of ordinary twine, it is necessary to provide an auxiliary receptacle to receive the ordinary balls of Manila binder-twine and to guide the twine from such balls and auxiliary receptacle and from the can.

Reference-sign A designates an auxiliary receptacle to receive the cops or balls oftwine when the ordinary Manila binder-twine is emthe bottom M of the can or casing A and to.

be bent outwardly against the under surface of such bottom, as most clearly indicated in Figs. 3 and 4.

Then the can is employed for grass bindertwine, the twine is led directly from the cop or ball through the free end of slack or tension arm D. When, however, the device is employed for ordinary Manila or similar twine, the twine is not led through the tension or slack arm D; but in accordance with the principles of my invention the twine is led through the opening in the top B, or rather in the cap P of such top, which when the device is employed for grass binder-twine forms the journal-bearing for the gudgeon or pintle L, such bearing-seat thus performing the double function of a journal-bearing for said pintle in the one case or as a guide-opening for the twine to pass through in the other case.' Pivotally mounted upon the cap I This tension-plate O is yieldingly pressed toward the cap P in any convenient manneras, for instance, by means of the spring D. At its free end the tension-plate C is provided with depending lugs (indicated at E) on the opposite edges thereof to form guides between which the twine leads, thereby forming a guide therefor.

The next feature of the improvement embodied in my present application relates to the manner of mounting and supporting the can upon the machine.

F designates a convenient part of the barvester-frame-,such, for instance, as the rear upright or standard. Suitably bolted or otherwise secured to this upright is a brace G, said brace being riveted or otherwise secured to the side of the can. A supportingbracket 0 is also bolted or otherwise secured to the upright or standard F and extends into position for the can to rest thereon. This bracket is provided with bosses, one arranged to receive the pivot-pin 11, about which arm D swings and which carries the brakingcam G, the other boss or stud formed in bracket 0 serving as the journalbearing for pintle or stud K.

From the foregoing description it will be seen that I provide a twine-can which is simple, inexpensive, and efticient and adapted for use with either grass binder twine or for ordinary Manila or other twine and which is i'lavingnow set forth the objectand nature adapted to receive the cop or ball of twine,
